ADS7950SRGET Equivalent & Substitute Parts

Part Overview

The ADS7950SRGET is a 12-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, part of the microPOWER™ series. This device features 4 single-ended inputs with a 1 Megasample per second (1M SPS) sampling rate and operates using a Successive Approximation Register (SAR) architecture with external reference configuration. The ADS7950SRGET is classified as Obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ADS7950SRGET is determined by strict equivalence across all electrical and mechanical parameters. The substitute parts identified maintain identical specifications for resolution (12-bit), input configuration (4 single-ended inputs), sampling rate (1M SPS), architecture (SAR), data interface (SPI), supply voltage ranges, operating temperature range, and physical package (24-VQFN with exposed pad).

The primary distinction between the main part and substitutes is packaging format and product status. The ADS7950SRGET is supplied in tube packaging and carries Obsolete status. The substitute parts are available in Tape & Reel (TR) packaging and maintain Active product status, ensuring continued availability and manufacturing support.

Key parameters determining substitution eligibility:

• 12-bit resolution
• 4 single-ended analog inputs
• 1M SPS sampling rate
• SAR architecture with external reference
• SPI serial data interface
• 2.7V ~ 5.25V analog supply range
• 1.7V ~ 5.25V digital supply range
• -40°C ~ 125°C operating temperature
• 24-VQFN (4x4) package with exposed pad

Parameter Comparison

Engineering Selection Recommendations

Both ADS7950SBRGET and ADS7950SBRGER are direct functional equivalents to the ADS7950SRGET. Selection between these substitute parts should be based on procurement requirements and supply chain considerations.

ADS7950SBRGET is designated as the MFR Recommended substitute, carrying Active product status with 2094 units in current inventory. This part maintains full parametric equivalence and is the preferred selection for new designs and ongoing production requiring the ADS7950SRGET functionality.

ADS7950SBRGER is classified as a Parametric Equivalent with Active product status and 3180 units in inventory. This part provides identical electrical and mechanical specifications and serves as an alternative source option.

Both substitute parts are supplied in Tape & Reel (TR) packaging format, which differs from the tube packaging of the original ADS7950SRGET. This packaging difference does not affect electrical performance or functional compatibility but may require adjustment to assembly and handling procedures.

All three parts maintain ROHS3 compliance, REACH Unaffected status, and identical moisture sensitivity levels, ensuring regulatory and environmental consistency across substitution options.

Frequently Asked Questions (FAQ)

Q: Can ADS7950SBRGET and ADS7950SBRGER be used interchangeably with ADS7950SRGET?

A: Yes. Both substitute parts are parametrically equivalent to the ADS7950SRGET across all electrical specifications, including resolution, input configuration, sampling rate, supply voltage ranges, and operating temperature. Pin configuration and package dimensions are identical, enabling direct board-level substitution.

Q: What is the difference between the substitute parts?

A: ADS7950SBRGET and ADS7950SBRGER are functionally identical. Both maintain Active product status and Tape & Reel packaging. The distinction is primarily in inventory availability and supply chain designation, with ADS7950SBRGET identified as the manufacturer-recommended option.

Q: Why is the original ADS7950SRGET marked as Obsolete?

A: The Obsolete status indicates that Texas Instruments has discontinued active manufacturing and support for this specific part number variant. The substitute parts in Active status provide continued design support and manufacturing availability.

Q: Does the packaging format change affect circuit design?

A: No. The change from tube to Tape & Reel (TR) packaging does not affect electrical performance, pin configuration, or functional operation. The packaging format impacts only procurement, handling, and assembly processes.

Q: Are there any compliance or certification differences?

A: No. All three parts maintain identical RoHS3 compliance, REACH Unaffected status, and moisture sensitivity levels (MSL 3, 168 hours). Regulatory and environmental certifications are consistent across the main part and substitutes.

Q: What supply voltage ranges are supported?

A: The analog supply voltage operates within 2.7V to 5.25V, while the digital supply voltage operates within 1.7V to 5.25V. These ranges are identical across all three part numbers.

Q: Is the SPI interface identical across all variants?

A: Yes. All three parts use identical SPI serial data interface configuration with no protocol or timing differences.
